Embodiment Construction

[0020] The following will refer to Figure 1 to Figure 12 One embodiment of a control device for a hybrid vehicle is described in detail.

[0021] Such as figure 1 As shown, the hybrid vehicle includes a power unit 10 that generates driving force that is transmitted to wheels 25 . The power unit 10 has two types of power sources, that is, an engine 11 and two motor generators, a first motor generator (hereinafter referred to as the first M / G 12) and a second motor generator (hereinafter referred to as the first M / G 12). II M / G 13).

[0022] The power unit 10 is provided with a planetary gear mechanism 17 having three rotating elements, namely a sun gear 14 , a planet gear carrier 15 and a ring gear 16 . The planet carrier 15 is connected to the engine 11 through a transaxle damper 18 . The sun gear 14 is connected to the first M / G 12 . The ring gear 16 is integrally formed with an auxiliary drive gear 19 . The counter drive gear 19 meshes with the counter driven gear 20 ...

Abstract

A power control ECU controls electric power and engine power of a hybrid vehicle. The power control ECU includes a request driving force calculating portion that calculates a request driving force calculated in accordance with an accelerator operation amount, a travel driving force calculating portion that calculates a travel driving force as a value that belatedly follows the request driving force, and a dashpot control processing portion. The dashpot control processing portion sets a value of the request driving force as a value of a final request driving force used to calculate request engine power when a difference of the request driving force with respect to the travel driving force is less than a predetermined positive value, and sets a value that belatedly follows the request driving force when the difference is greater than or equal to the predetermined positive value.

Description

technical field [0001] The present invention relates to a control device for a hybrid vehicle that travels by a driving force generated by a power unit having two types of driving sources (ie, having an engine and a motor generator). Background technique [0002] Japanese Laid-Open Patent Publication No. 2010-155532 discloses a conventional control device for a hybrid vehicle. The control device calculates a requested driving force from the accelerator operation amount, and controls the output of the engine and the torque of the motor generator so that the power unit generates a driving force based on the requested driving force. The control device increases or decreases the driving force generated by the power unit in conjunction with the increase or decrease of the accelerator operation amount. [0003] The hybrid vehicle described above needs to suppress vehicle body vibration caused by a rapid decrease in driving force when the accelerator is deactivated. Thus, torque ...
